For air-conditioner fan motor
3-Phase Brushless Fan Motor
Driver
BM6202FS
General Description
This motor driver IC adopts PrestoMOS™ as the output
transistor, and put in a small full molding package with
the high voltage gate driver chip. The protection circuits
for overcurrent, overheating, under voltage lock out and
the high voltage bootstrap diode with current regulation
are built-in. It provides optimum motor drive system for a
wide variety of applications by the combination with
controller BD6201X series and enables motor unit
standardization.

6) Fault signal output
When the gate driver detects either state that should be protected (UVLO / TSD / OCP), the FOB pin outputs low (open
drain) for at least 25µs nominal. The FOB pin has wired-OR connection with each phase gate driver chip internally, and
into another phase also entering the protection operation. Even when this function is not used, the FOB pin is pull-up to
the voltage of 3V or more and at least a resistor with a value 10k or more. Moreover, the signal from the outside of the
chip is not passed because of the built-in analog filter, but the internal control signals (UVLO / TSD / OCP) pass the filter
(2.0µs Min.) for the malfunction prevention by the switching noise, etc.
